What it tells you
A score of 115 is clearly above average. People in this range typically find abstract and academic material easier than most, but the score says nothing about effort, interests or skill in any particular field.
Scores in this range are common among university graduates, which is a statement about who goes to university as much as about the score.
How sure can you be of a score of 115?
That depends on the test. On a long, supervised assessment the margin of error is a few points. On a short online test it is around ten, so a reported 115 means a true score probably somewhere between 104 and 126. That span runs from the 61 to the 96 percentile.
Scores also depend on the scale. If your 115 came from a test using a standard deviation of 16 or 24, it is not the same as 115 here; the percentile calculator converts between them.
